Really interesting article in the NYT about the radicalization of American born Anwar al-Awlaki. He now has been targeted for killing by the U.S.
The article tells how he went from a mild mannered Muslim, to a hardened jilhadist. It is pretty interesting, especially how in Yemen prison he read the father of modern jihad, Sayyid Qutb.
